Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
An invalid supporting structure comprising a resilient, sponge-like pad having at least one aperture extending from the top to the bottom of the pad and located at a position adapted to register with a predetermined area of a received person, a pair of laterally extending conduits in the pad extending from the aperture to the side wall of the pad and means for passing a gas into and venting the gas from the aperture coupled to one of the conduits, the pad having a thickness varying along its longitudinal dimension in accordance with the weight distribution and physical contour of a person and wherein the density of the pad combined with the variation in thickness prevents a complete compression of the pad when receiving a person and provides a uniform support for the body over the supported area.
Claim 2
Dependent Claim
138 words
An invalid supporting structure comprising a resilient, sponge-like pad having at least one aperture extending from the top to the bottom of the pad and located at a position adapted to register with a predetermined area of a received person, a pair of laterally extending conduits in the pad extending from the aperture to the side wall of the pad and means for passing a gas into and venting the gas from the aperture coupled to one of the conduits, the pad having a thickness varying along its longitudinal dimension in accordance with the weight distribution and physical contour of a person and wherein the density of the pad combined with the variation in thickness prevents a complete compression of the pad when receiving a person and provides a uniform support for the body over the supported area.
Claim 3
Dependent Claim
17 words
An invalid supporting structure as defined in claim 1 wherein the skin of the pad is impervious.
Claim 4
Dependent Claim
28 words
An invalid supporting structure as defined in claim 1 wherein the aperture is located at a position adapted to register with a bony area of a received person.
Claim 5
Dependent Claim
28 words
An invalid supporting structure as defined in claim 3 wherein the aperture is located at a position adapted to register with the coccyx area of a received person.
Claim 6
Dependent Claim
125 words
An invalid supporting structure as defined in claim 1 wherein the pad is provided with an aperture located at a position adapted to register with the coccyx area of a person and with a pair of apertures spaced outwardly from said first aperture, said spaced apertures located at positions adapted to register with the bony hip areas of a person as the person is turned from side to side, a pair of laterally extending conduits in the pad for each of the apertures extending from each of the apertures to the side wall of the pad and means for passing a gas into and venting the gas from one or more of the apertures coupled to one of the conduits of a pair of conduits.
Claim 7
Dependent Claim
38 words
An invalid supporting structure as defined in claim 1 wherein the pad is adapted to support a person from the thoracic area downwardly and the pad is bifurcated to provide a relief slot from the pelvic area downwardly.
Claim 8
Dependent Claim
42 words
An invalid supporting structure as defined in claim 1 adapted to support a person over the thoracic area, the pad having an aperture located at a position adapted to register with the upper portion of the spinal column of a received person.
Claim 9
Dependent Claim
103 words
An invalid supporting structure as defined in claim 7 wherein the pad has a pair of apertures spaced outwardly from said first aperture, said spaced apertures located at positions adapted to register with the bony shoulder areas of a person as the person is turned from side to side, a pair of laterally extending conduits in the pad for each of the apertures extending from each aperture to the side wall of the pad and means for passing a gas into and venting the gas from one or more of the apertures coupled to one of the conduits of a pair of conduits.
